DEVICE FOR PREVENTING RAILS SHIFTING OR CREEPING.

Specification of Letters Patent.

Patented m 7, 1908.

To all whom it may concern:

Be it knownthat I, ANTONDAMERIS, subi'ect of the German Emperor, residing at Co- 0 e, Germany, have invented new and usefu Im rovements in Devices for Preventing Rails hitting or Creeping, of which the following is a specification.

The resent invention has for its object a device. or preventing rails shifting or creepplaced each with two hooks round the foot of the rail are employed, the one of which clam s abutting against the sleeper lying in the irection in which the rail'shifts. Both clamps lie against one another with sloping faces in such a manner that the clamping action is increased with certainty by the shifting movement. Also the action of this device is particularly iowerful because the foot of the rail is clasped by four hooks in all.

In order that the invention may be clearly I understood, reference is made to the accomanying drawing in which one embodiment is re resented byway of example and in which Figure 1 is a side elevation showing the de vice and the manner in which it is em loyed;

Fig. 2 is a plan of a rail with clamps t iereon;

Fig. 3 is also a plan showing the clamps in the position before they are attached to or moved entirely away from the rad, whereas Fig. 4 1s a vertical section in the plane A E 1n Ihe new device consists of two like plateshaped bodies or clamps a, a which at the one end at b, b are bent downwards nose-shaped and at the other end at c, c are sloped away laterally. On their long sides these plates have at both sides an n wardly bent hook d, e and d, e. These hoo s are preferably displaced relatively to one another in the longitudinal direction and, of course, are at a distance from one another in the transversedirection about equal to the breadth of the foot f of the rail I In order to arrange the clam ing device on the foot of the rail, one of the chlmping plates (1 is first placed against the footof the rail from below slan twise of the latter (Fig. 3), isthen turned so far horizontally that the hooks d and e clasp the foot of the rail, and lastly is pushed. so far towards the slee er situated in the direction in which the rai shifts until the nose 5 of the clamp hits against it; the direction in which. the rail shifts or creeps is indicated by arrows in Figs. 1-3. The other clamping plate a, is then brought on to the foot of the rail in similar manner in the opposite position, rotated and pushed against the first plate, so that the sloped ends c, c of both )lates abut against each other. The two p ates are then pressed iirmly against each other by means of a few blows of the hammer directed against the second clamping plate (1, whereby the hooks (l, e and d, c are clamped immovable on the foot of the rail, the plates acting as levers "when the sloped ends 0 c slide one on the other. It is clear that the clamping action, that is to say the frictional resistance between the hooks and the foot of the rail, is at once increased when the rail commences to creep and that this movement at once ceases in this manner.

What I claim as my invention and desire to secure by Letters Patent is:

The combination with a rail and a sleeper supporting the same, of a, pair of like clamps provided with a hook at each side adapted to clasp the foot of the rail and having one end sloped oil laterally and the other end bent downwards, whereby said clamps are attached to the foot of the rail oppositely, contacting one another with their sloped ends and the bent end of one clamp abutting against the sleeper.

In testimony whereof I have signed my name to this specification in the presence of two subscribing witnesses.

ANTON DAMIJRIS.
